The MAX643ACSA+ is a fixed output 10W CMOS step-up switching regulator in 8 pin NSOIC package. This regulator is preset to +15V output voltage however it can be set to other levels by adding 2 resistors. Device is designed for minimum component DC-DC converter circuit in 5mW to 10mW range. It is used in uninterruptible board level power supplies, power conditioning for battery systems and portable instruments and communication.
Operating voltage range from 2V to 16.5V
Oscillator frequency is 50KHz at Vout = +15V
Oscillator duty cycle is 50%
Supply current of 0.75mA at Vout = +15V
Internal reference voltage of 1.31V at TA= +25°C
Typical efficiency of 80% (with external MOSFET)
Line regulation of 0.08%Vout, operating temperature range from 0°C to 70°C
